The formation of loops and meshes, which, formed along the fabric base2, according to the design desired, represents the crochetwork, isefi'ected like the known chain'- stitch-mesh formation and can be seenfrom Figs. l, 5 and 8: The advanced needle 23 pierces the fabric base 2and, upon its re turn movement, the looper-point of the looper 18, whichswings always toward the middle of the looper supporting-head, catchesthe thread-loop 41, as the push-rod 12 is drawn outward by thedouble-armed levers 11. The looper 18 holds the loop fast, drawing thesame upon its return movement somewhat downward, until upon the next advance of the needle 23 the loop a1 gets gradually loose for the passageof the needle and falls off from the looper-point. A particularcharacteristic of the invention is that the looper 18 and the needle 23accomplish rotary movements in the same direction and thelooper 18swings with its point always toward the middle of the looper supportinghead, to which also the needle is directed. The thread is drawn to thatdirection in which the pantograph-pin is moved, and in the samedirection also the looper-point must swing and, therefore, needle andlooper must be turned accordingly. Supposing, forinstance, that thepantograph-pin is, after formation of the thread-loop on the looper(Fig. 5) and upon a complete return of the needle (for instance into aposition between that shown in Figs. 5 and 8), moved in the direction ofarrow III (see front view ofthe looper 18, Fig. 6,) also the needle 23and the looper 18 must, for obtaining a cor- 'rect loop-formation,receive a corresponding fabric by means of acids, chlorid or similarmeans, for instance by the known drying process, correspondinglymultiple loose crochet goods are obtained, which from hand crochet-workcan be hardly distinguished.

I claim a In an embroidering machine, the combination of reciprocatingand rotary needleslides, needles secured thereto, swingmg and rotaryloopers to co-act with the needles for the formation of chain-stitches,a driving spindle, worms connected to the slides and loopers,w0rm-wheels to gear with the worms, bevel-gearings to connect the worm-vwheels with the driving spindle, and means to allow part of thebevel-gearings to par ticipate in the reciprocating movement of theslides, substantially as and for the purpose set forth.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.

OTTO WALTHER.
